Subject: [ruby-core:55327] [ruby-trunk - Feature #6373] public #self


Issue #6373 has been updated by laise (Alexey Chernenkov).


Quote: "I think that tap method can be improved to be used without block yielding self."

It is a VERY usefull feature! Can't understand why #tap still need to be used with block only.

=begin
This was recently suggested to me as an extension:

  class Object
    # An identity method that provides access to an object's 'self'.
    #
    # Example:
    #   [1,2,3,4,5,1,2,2,3].group_by(&:identity)
    #   #=> {1=>[1, 1], 2=>[2, 2, 2], 3=>[3, 3], 4=>[4], 5=>[5]}
    #
    def identity
      self
    end
  end

First, is such a method commonly useful enough to warrant existence?

Second, it makes me wonder if #self should be a public method in general.
